MYB2 — Phaseolus vulgaris

Summary

PvMYB2 (PHAVU_006G105200) on French bean chromosome 6 encodes a Myb_TF_plants family transcription factor with sequence-specific DNA binding and transcription cis-regulatory region binding activities. It is localized to the nucleus. The gene is associated with pigment accumulation in tissues, phlobaphene biosynthetic process, and pigment biosynthetic process involved in pigment accumulation. It is linked to upregulation of phytoalexin biosynthesis, defense response to insects, and response to wounding, as well as regulation of lignin anabolism and flavonoid anabolism. PvMYB2 is also associated with response to stress, cold, and auxin, and to both upregulation and downregulation of DNA-dependent transcription. Studies of related genes in other species link the family to anthocyanin content and salt tolerance.
